DOUBLE-CHECK

Before you apply power, it 

is good practice to double-

check that you have the 

components in the right 

spot and soldered correctly.

Make sure the transistor and 

two LEDs are in the circuit 

board the correct way. If 

not, you need to de-solder 

the component and solder 

it in the right way. See our instructions opposite about de-

soldering.

Look closely at all of your solder joints and make sure they all 

look like “volcanos” as we described on page 2. If not, apply 

the soldering iron again and add a tiny bit of solder to make 

the solder joint reliable. Make sure all of the component legs 

are trimmed so they are not short-circuiting each other.

Finally, make sure you don’t have any bridged solder joints 

where one solder joint has joined with another because 

of too much solder. If this is the case, follow the de-solder 

instructions opposite to remove the solder, and then solder 

again.

POWERING IT UP

Insert a CR2032 battery (We 

recommend, SB2522) and 

your Owl’s LEDs should 

light up when you touch 

the round touch plate on 

the front of the Owl’s circuit 

board with your finger. 

Note: If the LEDs are not 

very bright when you touch 

the sensor, it may mean your 

finger is too dry. You will need 

to moisten your finger slightly  

and try again. 

Note: Your owl’s design will 

differ to the one shown here.

TROUBLESHOOTING GUIDE

If your badge doesn’t work:

1. Make sure your battery is not flat. Try using a fresh battery.

2.  Recheck all of your solder joints (review the soldering 

guide on page 2)

3.  Make sure you don’t have any short-circuits because of 

component legs touching or solder pads on the circuit 

board bridged together.

If the red LEDs are very dim, make sure you are using a fresh 

battery. If they are still dim with a fresh battery, double-check 

that you inserted the resistors into the right spots. If you 

still can’t get the badge to work, you can show the circuit 

diagram (shown below) to an electronics enthusiast who can 

help fault-find it with you.

DE-SOLDERING

In the unfortunate event that you need to remove a 

component, you need to de-solder it from the circuit board. 

You will need asolder sucker (We recommend, TH1862)  or 

Desolder braid/Solder Wick (We recommend, NS3020) to do 

this. If you are using a solder sucker, heat the solder joint to 

melt the solder and use the pump to suck the solder away. If 

you are using de-solder braid, you place that over the solder 

joint, apply heat, and you will see the solder be soaked up 

into the braid. Insert the component the correct way and 

solder again.
